“Without a doubt she had something done, probably two Brazilian butt lifts,” said plastic surgeon Dr. John Zannis. Dr. Zannis said Kim most likely lipo-suctioned the fat from her torso, stomach, love handles and lower back and had it injected into her buttocks.

However, Kim has long insisted that her face and body are 100% natural. At this point, though, does it really matter? She looks hot.

Kardashian, who was viciously fat-shamed during her pregnancy, had previously vowed to pose nude once she slimmed down after giving birth, so her nude photo spread isn’t surprising.

In addition to accelerating weight loss, the low-carb, high-fat Atkins and ketogenic diets have been touted for fighting depression and bipolar disorder.

Dietitian Dr. Jeff Volek, a professor at Ohio State University, agrees. “It was nothing short of an epiphany when I changed to a ketogenic diet 20 years ago,” Dr. Volek, author of the Art and Science of Low-Carbohydrate Living, told me. “I felt better, more satiated, and had more consistent energy.”

Kardashian’s low carb weight loss brought low-carb diets squarely into the mainstream. At this point, it appears Kim can sell just about anything. She’s a bona fide mover-and-shaker, in every sense of the word.
